This presentation will discuss the latest additions done to the LTTng project: the UST user-space tracer, the Eclipse Linux Tools Project LTTng integration, and user-space static tracepoints integration with gdb. An update on the latest LTTng roadmap will also be presented. The LTTng move from GPLv2 to dual LGPLv2.1/GPLv2 licensing will be explained.
This session is a hands-on tutorial on how to use the LTTng tracer. It presents the steps required to record a trace in the various operation modes of the tracer. The performance overhead trade-offs will be discussed. Navigation in a trace with the LTTV trace analyzer, including tips and tricks on how to best use the LTTV plugins will be demonstrated.
